A vaccine against HIV will be trialed in South Africa later this year after meeting the criteria needed to prove it could help fight the epidemic in Africa.
In 2015, 2.1 million new infections were reported — two-thirds of which occurred in sub-Saharan Africa.
A small trial, known as HVTN100, took place in South Africa in 2015 to test the safety and strength of immunity the vaccine could provide, ahead of any larger-scale testing in affected populations.
Fifty-two healthy volunteers were enrolled to receive either the vaccine, known as ALVAC-HIV/gp120, or a placebo to compare the extent of immune response generated. The results were presented Tuesday at the 21st International AIDS Conference in Durban, South Africa.
